I want to activate Vorticity in CFX Post to help analysis. But problems came out.
An erroe message,
"CCLAPI::validateData - CCL validation failed with message:Error: The essential parameter 'Option' is missing from /LIBRARY/VARIABLE:vorticity ",
displayed when I add the section below into Library. VARIABLE: vorticity Output to Postprocessor = Yes END

Alternatively, I selected the variable Vorticity in output control. After 1 iteration, I run the CFX Post to visualize the vorticity contour. But an other error came out, which says,"DataReader::loadData - Error reading file 'D:\run_001.res': Error reading dataset G/COMMANDS"
Why these happened?

I know editing the VARIABLES file in the root directory is an efficient way, but I want to know why the two errors took place.
